SPECIFICATION forming part of Letters Patent N o. 734,326, dated J uly, 21, 1903. Application filed October 20, 1902.. Serial No. 127,998. (No model.)l

T0 all whom it may concern,.-

Be it known that I, THOMAS P. Hicks, a citizen of the .United States, and a resident of the city of New York, borough of the, Bronx, in the county and State of New York, have invented a new and Improved Device for Fas-V tening Metal or Woodwork to Stone, of which the following is a full, clear, and exact description.

My invention provides a novel socket an means whereby it may be secured in a stone or in a wall for receiving al bracket or other suitable device for attaching to the stone or wall any desired article ofwood or metal.

The invention will be hereinafter particularly described and then defined inthe claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a longitudinal sectional view showing the socket member in place in a stone and before being expanded. Fig'. 2 is' a similar View showing the socket expanded, together with a plug for expanding the sockety and Aa driving-tool for the plug; and Fig. 3 shows the expanded socket in side elevation and as an example a bracket secured therein,

the view showing the stone in. section.

The socket A to be inserted in a hole s unk in the stone, as l0, is threaded, asatlct, or formed with an equivalent grooved'or roughened exterior'to engage the stone and prevent longitudinal displacement, and an expanding member in the form of a plug B is employed to expand the socket, any suitable drivingtool 15 serving when struck with a hammer to drive the plug. gitudinally, as atct, to facilitate expansion, and toward the inner end the socket is thickened, as at d2. The slits a' terminate short of the inner end of the socket. VThe increased thickness gives strength to the socket and produces a reduced diameter at said thickf ened portion. The plug B is of greater diameter than the socket at the thickened portion, whereby when the plug is driven by a blow on the driving-tool 15 the slitted portion of the socket is expanded to a firm engagement with the stonevlO. The inner endlof the socket has an inwardly-projecting flange a3 to produce a broad surface at the end,

The socket is slitted lonover a closed end in that the socket may bel more readily cast.

' The outer end of the plugB has aliange or head b, (seeFig. 2,)v which guides the plug by fitting the bore of the socket and also assists in preventing the driving of theplug through the inner end of the socket, since it will come to a bearing against the shoulder d4, formed at the thickened portion of the socket.

,.I have shown in Fig. 3 a bracket 20, which provides a pintle for a` shutter 2l; but any other desired article may be fastened in the socket by a threaded connection, as at a5, or

other fastening means, as will be readilyunderstood.-

- By the described constructionof socket I am enabled to do away with an extra sleeve to fit within the socket for receivingr the expansiveforce of the plug. An-example of such a sleeve is seen in Letters Patent No. 690,284, granted 'to me onDecemberSl, 1901.

While the sleeve construction is necessary in certainclasses of work, the presentarrangement is preferable in some cases, besides being simpler and less costly. v p

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. A" fastening device, consisting of an expansible socket having an integral portion thereof formed with a reduced diameter and longitudinal slits,`the said slits terminating short of the inner end of the socket, and an expanding member-'larger in diameter and adapted to be forced into said integral portion of the socket.

2. A fastening device, consistingofasocket of reduced diameter and increased thickness at a point toward the inner end, and an expansion-plug adapted to be driven in the socket and of a diameter larger than the reduced diameter of said socket, the -reduced diameter of the socket producing a. shoulder and the said plug having a ilanged head.

IOC

3. A fastening device, consisting of a socket 4 1o shoulder, and an expansion-plug having a anged head, the longitndinalslits of the socket terminating short of the inner end.

In testimony whereof I have signed my naine to this specification in the presence of two subscribing Witnesses.

THOMAS I). HICKS.
